We've been carrying a patch to make CPUMASK_OFFSTACK selectable
without debugging for a long time now. The comment said this was
going to be replaced with something else but that never seemed
to happen. We're carrying it to have a higher number of CPUs but
at this point I don't think it's worth it since the upper bound is
now 512. This should be enough for most Fedora use cases so just
drop the patch.

-Subject: [PATCH] lib/cpumask: Make CPUMASK_OFFSTACK usable without debug
- dependency
-
-When CPUMASK_OFFSTACK was added in 2008, it was dependent upon
-DEBUG_PER_CPU_MAPS being enabled, or an architecture could select it.
-The debug dependency adds additional overhead that isn't required for
-operation of the feature, and we need CPUMASK_OFFSTACK to increase the
-NR_CPUS value beyond 512 on x86. We drop the current dependency and make
-sure SMP is set.
-
-Bugzilla: N/A
-Upstream-status: Nak'd, supposedly replacement coming to auto-select
